 On their way home, the Kaiapoi men fell upon and killed a nephew of the important chief Taununu, whose pā was at Ripapa Island.Instead of taking his reprisal by attacking Kaiapoi—probably because of the strength of that fortress—Tanunu attacked Whakaepa (Coalgate), a small but populous offshoot of Kaiapoi, and killed all its people.Kaiapoi was now more deeply involved in the feud.
